How Furnaces Work: The Essentials Every Homeowner Should Know

Understanding your furnace helps you spot problems early and communicate effectively with your HVAC Contractor. Here’s a simplified overview of how a typical gas furnace works in Roseville homes:

• Thermostat calls for heat
• Control board starts the draft inducer motor to move combustion gases
• Pressure switch verifies proper draft
• Ignition sequence begins (spark or hot surface igniter)
• Gas valve opens; burners ignite
• Flame sensor proves flame; the system continues running
• Heat exchanger warms up
• Blower fan pushes warm air through ducts
• Limit switches ensure safe temperatures
• Exhaust gases exit via flue or PVC vent

Key safety components:

• Flame sensor: Confirms a stable flame. If dirty, the furnace will shut down.
• High limit switch: Prevents overheating by turning off the burners.
• Pressure switch: Verifies airflow through the flue to prevent backdrafting.

When any of these components fail—or when airflow is restricted—the furnace may lock out for safety. That’s a good thing, even if it’s inconvenient. Never bypass safety controls.

The Most Common Furnace Problems in Roseville, Explained

Roseville’s seasonal patterns—cool, damp winters and warm summers—create specific stresses on HVAC systems. Let’s break down the usual suspects and what they mean.

1) Dirty or restricted filters

Safety First: Carbon Monoxide, Gas Leaks, and Combustion

Nothing outweighs safety in heating systems. Gas furnaces, when installed and maintained properly, are safe and efficient. But the stakes are high.

• Carbon monoxide (CO):

• Odorless and dangerous. Install CO detectors on each level and near sleeping areas.

• Annual combustion testing ensures proper CO levels and safe draft.

• Gas leaks:

• Rotten egg smell indicates a leak. Leave the home immediately and call the gas utility.

• Do not operate electrical switches or phones inside the home if you suspect a leak.

• Backdrafting:

• Negative pressure can pull exhaust into the home. A proper venting system and combustion air supply are critical.

• Watch for soot, melted plastic, or rust around the vent.

• Heat exchanger integrity:

• Cracks can allow CO to mix with air. Professional inspection is essential if you notice soot, flame roll-out, or unusual smells.

• DIY boundaries:

• Homeowners can replace filters, clear drains, and manage thermostats.

• Leave gas, combustion, and electrical repairs to licensed pros.

Understanding Error Codes and Diagnostics

Most modern furnaces include onboard diagnostics—LEDs that flash sequences or display numeric codes. These codes point to areas of failure:

Common codes and their general meanings:

• Pressure switch open/closed faults: Venting or inducer issues
• Limit switch open: Overheat condition, airflow restrictions
• Ignition failure: Igniter or gas valve timing
• Flame sensor fault: Flame not proven
• Communication error: Thermostat/control board issues

Pro technicians complement code reading with:

• Multi-meter tests (voltage, resistance, current)
• Manometer readings (gas pressure)
• Combustion analyzer reports (O2, CO, efficiency)
• Static pressure tests (duct performance)

Ask your HVAC Contractor to walk you through code meanings and share readings. That transparency builds trust and helps you make informed decisions.

• Waste conditioned air in attics and crawlspaces.

• Long, restrictive runs:

• Deliver weak airflow to far rooms.

• Crushed flex duct:

• Reduces capacity dramatically.

Solutions:

• Add or enlarge return pathways.
• Seal with mastic and tape rated for ducts (not cloth duct tape).
• Replace damaged flex with rigid duct and smooth radius fittings.
• Balance the system with dampers and airflow measurements.

A well-designed duct system reduces noise, improves comfort, and extends furnace life by reducing strain.

Indoor Air Quality During Heating Season

Heating season can aggravate indoor air quality (IAQ) issues:

• Dry air:

• Consider a whole-home humidifier to maintain 30–50% RH. Proper humidity reduces static, protects wood, and improves comfort.

• Dust and allergens:

• Use quality filters and maintain a clean home. Seal duct leaks to prevent dust infiltration from attics and crawlspaces.

• VOCs and stale air:

• Increase ventilation strategically. An ERV can exchange stale indoor air for fresh outdoor air while conserving heat.

• Odors:

• Persistent odors can indicate combustion or mold issues. Investigate promptly.

Ask your HVAC Contractor about IAQ monitoring and solutions that won’t compromise system airflow.

Maximizing Thermostat Performance for Efficiency and Comfort

The thermostat is the command center for your furnace. A few optimization tips:

• Placement:

• Mount on an interior wall away from direct sun, drafts, or heat sources.

• Programming:

• Use set-back schedules that align with your routine.

• Avoid extreme set-backs that cause long recovery times and discomfort.

• Smart features:

• Geofencing, occupancy detection, and adaptive recovery can fine-tune comfort while minimizing energy waste.

• Advanced controls:

• If your furnace is two-stage or modulating, ensure the thermostat supports staged heating.

• Calibration:

• If temperatures feel off, calibrate or adjust the thermostat. Some smart thermostats learn your home’s thermal behavior.
